Which database model organizes data in tables?

• A. Hierarchical model
• B. Object-oriented model
• C. Relational database model
• D. Network model

Answer: (C)

The relational database model organizes data in tables, which are also referred to as relations. Each table consists of rows and columns, where rows represent individual records and columns represent attributes of those records. This model utilizes a structured query language (SQL) for data manipulation, allowing users to easily perform operations such as inserting, querying, updating, and deleting data. The design of the relational model allows for straightforward connections between different tables through the use of foreign keys, enabling complex relationships and data integrity. This tabular organization makes it intuitive to understand and work with the data, which is one of the reasons this model has become widely popular for database management systems. In contrast, other database models like the hierarchical model organize data in a tree-like structure, where each record has a single parent and can have multiple children, leading to less flexibility. The object-oriented model focuses on representing data as objects, similar to object-oriented programming, rather than in a tabular format. Lastly, the network model uses a graph structure to represent records and relationships, allowing multiple relationships between different records, which adds complexity compared to the simplicity and clarity of tables in the relational model.
